This deep groove ball bearing carries a single row of balls in Generation C construction, with a bore of 12.0 mm, an outside diameter of 32.0 mm, and a width of 10.0 mm, giving a net mass of 0.036 kg. Both sides are fitted with metal shields (2Z), and the ball complement runs in a steel sheet metal cage (JN). The limiting speed reaches 31500 1/min, with a reference speed of 24600 1/min, and radial internal clearance is set to C2, below the standard range. The reduced C2 clearance suits applications where operating conditions would otherwise push the effective clearance toward the higher end, allowing tighter fits or thermal expansion without excessive internal play. The steel sheet metal cage keeps mass low and supports the high permissible speeds, while the double-side shields protect the raceway and ball set from coarse contamination without providing full sealing, which points to environments with moderate demands on sealing but reliance on the bearing's own grease fill for lubrication over its service life.
